Comprehensive Dissolution Study on Two Double Ce(IV) Phosphates with Evidence of Secondary CeO₂ Nanoparticle Formation [PDF]

Molecules
Herein, we present a comprehensive study on the dissolution behaviour of two sodium–cerium(IV) phosphate phases synthesised hydrothermally from CeO2 nanoparticles: crystalline Na2Ce(PO4)2 and nanocrystalline NaCe2(PO4)3.

Metal-Salen-based Probes for the Selective Detection of Phosphates via a Disassembly Approach

CHIMIA, 2020
Polyoxophosphates are ubiquitous in nature and play important roles in biological systems and in the environment. Pyrophosphate (PPi), an important member of this family, is produced in over 200 biochemical reactions and is a marker in clinical diagnosis.

Kinetics, Isotherms, and Thermodynamic Modeling of the Adsorption of Phosphates from Model Wastewater Using Recycled Brick Waste

Processes, 2020
Phosphates in wastewater at elevated concentrations cause eutrophication of water bodies and their removal from treated wastewater is essential before effluents are discharged to the environment.

Buffering Capacity and Effects of Sodium Hexametaphosphate Nanoparticles and Fluoride on the Inorganic Components of Cariogenic-Related Biofilms In Vitro

Antibiotics, 2022
Despite the remarkable effects of sodium hexametaphosphate nanoparticles (HMPnano) on dental enamel de-/re-mineralization processes, information on the effects of these nanoparticles on biofilms is scarce. This study assessed the effects of HMPnano, with

Fluctuations of mineral nitrogen and phosphate in river water during periods of various wetness

Journal of Environmental Engineering and Landscape Management, 2005
Biological indicators are the best indicators of water quality, since they are interpretive of a variety of Stressors. Analysis of scientific literature shows that substance flows are calculated using different methods.

Synergy between conventional phosphorus fire retardants and organically-modified clays can lead to fire retardancy of styrenics [PDF]

, 2003
Polystyrene–clay nanocomposites combined with phosphorous-containing fire retardants have been prepared and used to explore the thermal stability and mechanical properties of the polymer formed. The amounts of fire retardants and clay used were varied to

Topological Features of the Alluaudite-Type Framework and Its Derivatives: Synthesis and Crystal Structure of NaMnNi₂(H_2/3PO₄)₃

Crystals, 2021
A new sodium manganese-nickel phosphate of alluaudite supergroup with the general formula NaMnNi2(H2/3PO4)3 was synthesized by a hydrothermal method. The synthesis was carried out in the temperature range from 540 to 660 K and at the general pressure of ...
